The status of three rare siphonophores (Cnidaria, Hydrozoa) described by Tamiji Kawamura: Bathyphysa japonica, Athorybia longifolia and Forskalia misakiensis [PDF]
The holotypes of three species inquirendae siphonophores collected in Japanese waters and described by Tamiji Kawamura were re-examined. It is considered that Bathyphysa japonica is not a valid species because there are no characters that distinguish it ...

Integrating siphonophores into marine food‐web ecology [PDF]
Siphonophores are a clade of understudied colonial hydrozoans (Cnidaria) that are abundant predators in oceanic ecosystems, with species present across the water column.

Characterizing the secret diets of siphonophores (Cnidaria: Hydrozoa) using DNA metabarcoding. [PDF]
Siphonophores (Cnidaria: Hydrozoa) are abundant and diverse gelatinous predators in open-ocean ecosystems. Due to limited access to the midwater, little is known about the diets of most deep-dwelling gelatinous species, which constrains our understanding

Global distribution patterns of siphonophores across horizontal and vertical oceanic gradients [version 1; peer review: 2 approved] [PDF]
Background Siphonophores are diverse, globally distributed hydrozoans that play a central role in marine trophic webs worldwide. However, they still constitute an understudied fraction of the open ocean gelatinous taxa, mainly due to challenges related ...

Trophic ecology of Octopus vulgaris paralarvae along the Iberian Canary current eastern boundary upwelling system [PDF]
Our knowledge of the diet of wild octopus paralarvae, Octopus vulgaris, is restricted to the first 2 weeks of its planktonic phase when they are selective hunters found near the coastline.

Impact of an eddy dipole of the Mozambique channel on mesopelagic organisms, highlighted by multifrequency backscatter classification. [PDF]
The impact of a cyclonic (C), an anticyclonic (AC) eddy and transition zone (TZ), which is the area between the two eddies, on acoustic groups representing various mesopelagic organisms, was investigated using a semi-supervised multifrequency ...

Dead zone or oasis in the open ocean? Zooplankton distribution and migration in low-oxygen modewater eddies [PDF]
The eastern tropical North Atlantic (ETNA) features a mesopelagic oxygen minimum zone (OMZ) at approximately 300–600 m depth. Here, oxygen concentrations rarely fall below 40 µmol O2 kg−1, but are expected to decline under future projections of global ...

Individuality and Aggregativity [PDF]
Why is there a specific problem with biological individuality? Because the living realm contains a wide range of exotic particular concrete entities that do not easily match our ordinary concept of an individual.

The Evolutionary History of Siphonophore Tentilla: Novelties, Convergence, and Integration. [PDF]
Abstract Synopsis Siphonophores are free-living predatory colonial hydrozoan cnidarians found in every region of the ocean. Siphonophore tentilla (tentacle side branches) are unique biological structures for prey capture, composed of a complex arrangement of cnidocytes (stinging cells) bearing different types of nematocysts (stinging ...
